The Spectrometer/Telescope for Imaging X-rays (STIX) on board Solar Orbiter continuously measures the Sun in energy range 4-150 keV. Due to spacecraft’s peculiar orbit, around 50% of all STIX flares are backside and lack a corresponding GOES class. In Stiefel et al. (2025) we describe correlation between background detector measurements where found power-law function two data sets. This can be used get proxy class large flares.Building up approach using STIX, want discuss how...
Context. We present an analysis of a GOES M1.8 flare with excellent observational coverage in UV, EUV, and X-ray, including observations from the instruments IRIS, SDO AIA, Hinode/EIS, Hinode/XRT, Solar Orbiter Spectrometer/Telescope for Imaging X-rays (STIX). Hard X-ray emission is often observed at footpoints loops occasionally corona. In this flare, four nonthermal hard sources are seen. Aim. Our aim to understand why we can observe individual how characterize physical properties these...
Models of particle acceleration in solar eruptive events suggest that roughly equal energy may go into accelerating electrons and ions. However, while previous X-ray spectroscopic imagers have transformed our understanding electron acceleration, only one resolved image γ-ray emission from accelerated ions has ever been produced. This paper outlines a new satellite instrument concept—the large imaging spectrometer for nuclei (LISSAN)—with the capability not to observe hundreds over its...
